gold or rare cameras?

I've been mostly collecting Sonnar lenses of late, and lenses that were not designed with the aid of a computer... I told that to an optical engineer that has since retired and his answer... "Brian, computers really did make it easier for us". My "Pride of the pack" is a 1936 Carl Zeiss Jena 5cm F1.5 Sonnar, all surfaces coated. It had never been opened, cleaned up beautifully. I did not realize the inner surfaces were coated until disassembling it- covered with haze. That's the fun of collecting, finding the pony in the bucket.
